Add a new segmentation rule to the Source language of your TM, such as this one:

Note: if there are different bullet characters in your text, you can add a new segmentation rule for each on them or take them all into account with this regex:

thank you so much.

Can I ask Studio to redo the segmentation now that I have this new rule... even though my document is already open?

Yes, I think that if you right-click on the file, select Update File and select the same source file, the new segmentation rules will be applied.

I will try, thank you again.

Well... nothing seems to work!

I copied the picture you sent for segmentation of the English text; I even copied the bullet used in the document! I saved the new segmentation rules under a new name, loaded it, redid the file from scratch... alas, still the bullets are not reckognized a segmentation ponctuation.... maybe because they are not in the drop-down list as items we can select.

Anyway, thank you for taking the time to try help me out.

Serge Dugas ,

Could you please confirm that the added segmentation rule is still in the TM you saved it?

Yes, when I click on my translation memory, I see it.

This looks like you created a Language Resource Template instead of adding the segmentation rule to the TM. To add the rule to the TM, right-clik on the name of the TM, select Settings, then Language Resources.

It would also help to see some sample text to see if this is actually the rule you need.

I have to manualy seperate the segments at the bullet... and I have 300 pages of those.

This is a PDF opened in Trados Studio 2022

I'll try what you just suggested... I thought the ressource template was the way to go.
