Batch editing of Project Settings Templates in Studio 2021

I have a lot of different project settings templates in Studio 2021 (relating to the kinds of penalties applied and which TMs are accessed, as well as in terms of Lookup/Concordance/Update) and typically would like to be able to add 2 file-based TMs to each and remove 1 file-based TM from each, or to change the drives they are stored on. Is there a way to do this in batches?

Would there be any particular risk to changing the .sdltpl file - e.g. by changing the yellow highlighted part in Notepad++?

<CascadeEntryItem PerformConcordanceSearch="true" Penalty="0" PerformUpdate="true" PerformNormalSearch="true">
<MainTranslationProviderItem Uri="sdltm.file:///XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.sdltm" Enabled="true" />

Thanks for any suggestions!
