Manipulating issue field options

Hello,

I’m trying to save some metadata on versions and then show (and filter out) it on the create / edit issue page to help to user choose it according to the metadata. The second part is the tricky one.
Going through the documentation, I’ve seen that the integration options with the issue page are the following:

  1. Custom field - seems unnecessary because I’m not saving anything new.
  2. Web-panel - I prefer not to show 2 dropdowns for the same field. (And also not sure if it will appear in the create / edit forms)
  3. Web Item (Actions) - Don’t see how to use it in this case.

Is there any other way I can manipulate the values in the select component of the version?

Thanks,
Roey
