If these are open-source templates from the Silverfin marketplace @lieels01 (and I have a feeling you reference to the BE legal text templates), there’s only one way and that is to look into the source-code of that template, which can be done on firm level.
In most cases, what I sometimes do, is look for a specific text in the source code to find the needed information, and then check the variables that are used.
You could also copy the source code as a new template on company level (more info on that here).
Unfortunately, the debug-mode for text templates on company level isn’t an option, but that doesn’t matter as results are not possible at all with these kind of templates anyway.
Please, let us know if this was of any help. We strive to open up as much data as possible so people can built custom templates, but there are lots of custom data in some cases, and in the case of BE legal texts, there’s no other option to search in the source code I’m afraid…
