Hi,

is it possible or planned to configure the tag event source via scripting? Given a high number of tags and the inability to use wildcards, a programmatic configuration approach would be beneficial, if feasible and if this makes sense.

I’m pretty sure wildcard paths do work, they are just only allowed at the end of the path like other places in Ignition that allow wildcard tag paths.

e.g. `[default]MyFolder/*`

Ah okay, I read the documentation and it says, you can only use wildcards at folder level but not on tags.

> Tag Event
> 
> The Tag Event source listens for any changes to a tag's timestamp, value, or quality. Users can subscribe to a single tag path, or a list of tag paths, configurable through the Insert Tag Insert Tag Icon icon on the right. **You can use wildcards at the folder level to help specify a path, but not at the tag level.**
