Possibility to modify "New Issue" dialog

Hello has anybody experience with modification of attribute showed during creating new issue. We added few attributes to issue object regarding customer request. Our customer wants now to invite to the platform people from shop flor but he request to make the dialog as simple as possible. 

My problem is that I am unable to hide some unnecessary attributes from the create issue dialog and even I am unable to modify their order. I can modify using mask management property tab of existing issue but not the one shown during create operation. The added attribute are at the end of dialog and in random order.
