Hello, is it possible to have a template of sorts inserted into the event body (HMTL editor) field?

E.g., we allow users to post social bike ride events, and would like them to comply with a certain structure to ensure they include all the key details. Is there a jEvents native plugin for this, or would one need to use one of the Joomla ones (e.g., Content Templater by Regular Labs)? Problem with the 3rd party ones is they allow inserting of the content template via a Joomla editor button (which is good), but it's available everywhere (including submitting articles - not good) while we'd love for this to only be available in jEvents, and even better when someone selects the category. (E.g., in our case, users are able to submit a variety of event types - social ride, advocacy, work party, social gathering, etc. ... we'd love for the template button to only be available when someone selects the "Social Ride" category).

Thought I'd post here first, and happy to move this to the enhancement request section.

Thank you for any pointers!
