Is a 'cross' an option in Adobe Sign?

Hi, I'm a Realtor and every one of our contracts have at least one change that needs to be initialed. The program that I'm using now does not have a cross as an option to drop into a document so that 4 people can initial a change. We're looking for a program that does have this option. Is there a way to drop in, or draw, a cross on documents with this program? We aren't going to sign up with a different company until we've found one that does what we want because right now we're printing each contract (minimum of 16 pages), making the changes and drawing a cross, then scanning the contract back in for signature. There's got to be a better way! I await your reply ...

Thank you in advance!
