Hi @Sarah_Cavanaugh , currently, this is not natively possible to do within Asana using Rules.
I was thinking perhaps a 3rd party integration could do this via the API but according to @Bastien_Siebman’s awesome post, it doesn’t seem this is supported.
pinging the API experts in case this could be custom coded… @Bastien_Siebman , @Phil_Seeman , @lpb
