Custom Code in Email Blocks - Please Please Please

Please please please for the love of goddess, give us the option to add a block in the Ontramail email designer for custom code. Please. So many other platforms let you do it and I'm so so so freaking sad that Ontraport won't let me unless I move ALLLLLLLLL of my messaging & campaign emails to your old email editor, which would be a total pain in the ass. 

Thank you!
