Plugin hooks for contribution actions

Development Plugin Development

Currently I am using some scripts in indico shell to e.g. assign poster board numbers in a batch operation.

I would like to improve this via plugin that adds these actions to the contribution list (like the current ‘Assign programm codes’ button). Are there any signals available to perform this hooking?

No, but feel free to send a PR that adds a template hook similar to the registration-status-action-button one to indico/modules/events/contributions/templates/management/contributions.html.
