Feature Request: Delete Note from Buyer and Custom fields 1-3

Hi shipstation team, 
i use the 3rd Party Fulfillment and The Store who is sending orders to me is setting values in this fields: 
Note from Buyer and Custom fields 1-3

I do not see an option to delete these fields with automatisation rules on Import as they are messing with my automatisations down the line. I only see SET field....  Could you make an option to Delete the Values of that fields or overwrite it, rather than just Add what you currently have ?

It would be a bonus if all those fields would be shown on detailed order view on the mobile app as well.

thank you
