Security on P98220W ( Web OMW)

Hello,

I have a requirement where I must grant some functional resources access to create versions and move them to a OMW project but restrict their other access like delete / advance a project etc. For this I am trying to lock down the web OMW with role security however I am unable to find what security to apply for the following.

1: The values of the drop down box in P98220W shown as #1 below

2: The Remove button #2 … is this Push button security ?

3 & 4: I want to disable the Advance / Change Project Status option

I know I can achieve this by changing the allowed actions/activity rules but for that I will have to make several changes to my existing setup. Any suggestions are appreciated
