SOW and clicks on the Teams button

[RupaliJ]

When a user opens up SOW and clicks on the Teams button, they should not see any Teams (Groups) where the Type field contains ‘Access group’.

This will apply to all the three filter options in the list button: Your teams, All SRM Teams, All teams

We would like to filter the list of teams too.
The issue is:
On the SOW homepage there's a button in the 'chrome_toolbar' on the left that is labeled 'Teams'.
We assume it was installed by the SOW Migration Utility. Although we could disable it, we would prefer to filter the list of teams it yields, because it shows ALL the groups the currently logged on user is a member of.
Many of the groups shown are for 'system' purposes and better hidden from the SOW user, such as granting them a role, access to specific reports etc. These groups being visible just cause unnecessary questions to the admins and confusion to the user.  It would help greatly if we can filter the  list of groups e.g. by the Type property.
But it seems not to be as easy as setting a filter on a table field. Does anyone know how to filter this group list?

I have a similar request to that needs to be customized. 
Just wanted to check if you guys had made an approach on the requirement without doing much of a customizations.
