restriction in Group picker

Hi All - 

I am using groupFilter option, but I need to restrict few groups from the suggested groups. Is there a way to get the Required Suggestions mentioned below.

Ex:

groupFilter: cons!GRP_XYZ

Suggested Values: {Grp_1, Grp_2, Grp_3, Grp_4}

Required Suggestions: {Grp_1, Grp_4}

Thanks/Mp
