Is it possible to change the contents of a custom field for a contact based on addition to a group?

I have smart groups controlled by custom fields.  I would like to clear two custom fields if the contact is moved into a certain group.

Is this possible and can anyone help me understand how this is done?

I know this is probably an idiot question, but I can't seem to get my mind wrapped around it.

Thanks for what ever you can offer.

Thanks Michael,

I am using a custom field with names of volunteer committees within it.   This field is included in an event signup form for people to select the committee they wish to volunteer for.  I have a bunch of smart groups, each based on a volunteer committee contained in that field.  So when someone signs up for the event and volunteers for a committee, they are made a part of the smart group for that committee.

To further complicate the issue, I would like to restrict access to only certain committees for new volunteers.  So I created a second field with only those committees and did a search builder for those committee smart groups that bunches the two fields into one smart group.

The issue I am having is that I would like the chair person for that committee to be able to easily switch the volunteer out of that committee and into another.  For example, they aren't good for my committee but would be fine somewhere else, so let's put them into "anywhere you need help" committee.

I am looking for a one step process, out of one group and into another.
