Pending auto close

[vendorsupport]

When we set a ticket to Pending Auto Close +/-, we have a notification that state something like "The ticket <OTRS_TICKET_ID> will be closed automatically in 24 hours."

However, instead of hard typing "24 hours", is it possible to create an OTRS Date tag/attribute so that when we change the Pending Date (for pending states), that it will automatically insert the Pending Date that we select?

Thanks in advance.
