What version of Adobe Sign do I need to replace a signer?

Hi. I used to have an online Adobe Esign account but have been told that Adobe now dont support that. I also have an Adobe DC account but it only does basic signing and wont let me 'replace a signer' which I really want as quite often I make a mistake and send it to a .co.uk address rather than a .com address! Dont want to have to cancel the whole thing and start again. Adobe say I need Small Enterprise edition which is for 9 users and a lot of money! Seems crazy that I cant just renew my current account with them. Any suggestions?
