Custom Category Event

Hello everyone,
i’ve been using this wonderful plugin for a lot of time, but now i’m having this issue:
– i’m using a plugin (events manager) that creates its own event categories and it handles them as wp does to its own.

How can i set for that event categories a custom sidebar with this plugin?
(i thought i could write a code telling the plugin to manage them in the way it does to the wp category in the Default Category panel. but i don’t know wich code i have to write.)

Please, can someone help me?

thanks a lot
