Need to modify 'chatter.discussion.store' route to check for permission

[yelnyafacee]

Hi, is there some way to modify the chatter.discussion.store route?

the route is pointing to DevDojo\Chatter\Controllers\ChatterDiscussionController@store

I saw in another issue here that recreating the class is impossible, so is there any way to modify @store to check for permission ( use permission to decide available input categories for the post ) ? Thanks
