Can ZTIGather parse multivalue strings?

I would like to have a custom setting assigned to a role that contains multiple values.

I'd like to make a role so that when a computer is assigned to that role, it is added to the AD groups specified in that roles AddToADGroups setting.

I have a setting in the MDTDB called AddToADGroups.  And I would like to list a variable number groups in that setting.

so something like AddToADGroups=Group1,Group2,Group3,Group4 

So the RoleSettings view in the MDTDatabase might look like this (shortened)

On the ZTIGather/Customsettings side. at the end of ZTIGather, I would end up with

a list variable AddToAGroups(*) with the values parsed into that list as AddToADGroups001=Group1,AddToADGroups002=Group2 and so on.

Is it possible to do this using CustomSettings.ini and ZTIGather or is there no way (out of the box) to store a list in MDTDB.

I am thinking CustomSettings would be something like (leaving lots out)

Priority=RSETTINGS,Default

Properties=AddToADGroups(*)

[RSETTINGS]
SQLServer=MySQL.domain.com
Database=MDTDB
Netlib=DBNMPNTW
SQLShare=SQLSHARE$
Table=RoleSettings
Parameters=Role

I hope this makes sense what I am trying to do.
