[midPoint] Delegated Admin Question

[Brad Firestone]

I'm working on a delegated admin role in midPoint 3.6.1 and can't figure 
out a couple of things:

1.  Is there any way to control the Types of objects that can be 
Assigned?  When working with an existing or new User, I click on the 
Assignments Tab.  Then click the "gear" icon, and choose "Assign".  The 
"Select object(s)" window opens and defaults to Type: RoleType.  I would 
like to ONLY be able to see Type: ServiceType and OrgType.  Is there a 
way to hide RoleType and ResourceType?

2.  Whether or not I can hide items as asked above, I'd like to know if 
thee's a way to have Type:ServiceType be the default selection.  Is 
there a way to define the default option here?

Thanks for any suggestions!
Brad
