How to avoid segmentation after notes superscript numbers

Question

Some colleague translators are having segmentation problems when they work with note superscript numbers at the end of a sentence. They end up with several sentences together in the same segment that should had been segmented after the superscript number. Some translators end up fragmenting all those segments manually in the Editor, while others modify the original document before creating their project in Studio and move the punctuation after the note superscript number to avoid this kind of segmentation problem. Both methods are very time-consuming. How can the segmentation rules be modified to deal with this problem? Is there any other way to solve it? Thanks in advance. 
 Example: 
 During the first 10 months after the pandemic was officially declared, alcohol and cannabis use 5-6 [ no problem here ] and depression 7 [ no problem here] increased, and self-rated positive mental health, life satisfaction and community belonging 8 [ no problem here ] declined, with no changes in suicidal ideation noted. 9 [should have been segmented] However, Canadians were not equally impacted. As Varin et al. 5 [ no problem here; should not be segmented ] maintain, &ldquo;understanding the social determinants of health is key to developing harm reduction and mitigation strategies.&rdquo;

 IMHO, manually splitting segments is very bad practice. It's time consuming and comes back to bite you if you have to update the file or work with a very similar file etc. I would avoid that at all cost. 
 Studio is pretty user-friendly when it comes to editing segmentation rules, but unfortunately it does not have a preview function (Hey, RWS, that would be cool.) There is a free tool called Ratel which does: 
 
 So you define an exception to the rule(s). If a number \d+ or two numbers seperated by a dash \d+-\d+ occur after a full stop, break. 
 In Studio, segmentation rules are stored in TMs, the first TM of your project is used for segmentation. So if you go into settings there, you can customize segmentation rules: 
 
 Add another rule and select "advanced view", then you get their default "new rule": 
 
 Now add your footnote definition to the "before the break": 
 
 I don't have the time to test this, but I am pretty sure this should work.
