@BusterCherry Apologies for the late reply on this. We don’t have this feature currently implemented, but we do intend implement a similar design that you’ve proposed.
The Templater Settings effect should have an additional parameter that is perhaps labeled something such as “Fallback Target Layer”. This param would essentially allow a user to specify different ways to “search” for a layer target if the one selected is not enabled / visible.
We have this in our queue for feature improvements and your post validates our need to have this in there.
In the meantime, you might be able to use an “invisible” video of varying lengths that can act as a proxy to what you want (i.e. a layer shifting in the timeline a certain amount of seconds / frames depending on your re-versioning data).
Please let us know if this helps or if we can provide more clarification.
Many thanks again for your patience!
Best,
Arie
