It would be helpful to have the ability to retroactively apply a matching gift to specific donations if the match was created or activated after the donor already contributed. Use case: A donor intended their gift to count as a match, but the match was not activated before the donation was made. Currently, the best workaround is to refund the donation and ask the donor to re-donate after the match is set up, which can create extra friction for both the donor and the organization. Requested functionality: Give admins the option to select eligible past transactions and apply them to an active match so campaign totals and match tracking remain accurate.
