It works the same way the cloud flow word template where you can populate the repeating table with the normal value. (you can use formatted value instead)

According to the documentation of the Word Online connector this should be possible https://docs.microsoft.com/en-us/connectors/wordonlinebusiness/#guide-for-using-repeating-section-content-control-in-the-word-online-connector

By the way, did you try to populate in PowerFlow subgrid (related records) for given entity ? In OOT word template you can repeat rows (special control) , but how about Power Flow ? – Populate a Microsoft Word template. in one record e.g. payment you can have multiple reviews to populate in Word template from sub grid. I am not sure it is possible to do at Power Flow at all

Alternative option is Documents Corepack for all projects
