Approval Signature


Hi, I use SMARTSHEET because it is intuitive. However I am wondering why there is no way to add an approval signature when approving forms. I do not want to use integrated apps where I have to pay. I see a lot of comments asking how to add signatures so I know it is needed. This is 2021, and I am just curious why SMARTSHEET does not have this option and will you have this option in the very near future?
