C4C - How to update a field on the Account or Individual Account right after adding a Relationship?

Hi All,

I'm trying to update a field on either the Account or Individual Account after adding a Relationship between them using the Relationships facet on the Account.

Is there a way to update a field on either the Account or Individual Account once the user presses Save on the bottom of the Account form. I'm just trying to update any field to get a record's modified date to change because it looks like the modified date does not change when a relationship is added.

Any guidance would help.

Thanks,
