Comment @SellerABC on a DealNote
Should be an easy1:
Would help a lot to notify specific sales colleagues that there is a relevant comment for them on a deal where this person needs to respond or decide for an action.
I know it from many other CRMs to simply comment e.g. @Inês Batata in a Deal Note and this person is notified.
Especially during increased remote work, this feature would help to foster asynchronous communication.
