Upload new Document while personalizing Sequence or Template send

@jennbudins @BeccaArmistead This would be a very useful -- was submitted 18 months ago - Is there hope?
I’m surprised this isn’t a feature actually, given that HubSpot is all about customizing automation to be ‘personalized automation’.
I tried the gmail copy paste.. copying the image from the message text box in gmail, over into the sequence in the Hubspot CRM , but no luck.
This would be an AWESOME feature.. Any update on this feature would be fantastic. Thanks!!
