Does workplace have the ability to edit and sign PDF forms? I am a current docs user, but for some reason I cannot edit or sign any prf forums while in docs.  Currently when I need to fill out an pfd form, I have to upload it to my personal google drive, use dochub to edit and sign the document, then upload it again to my zoho docs so I can share it with my staff, this is a very inefficient way of doing things.  Being in the service industry I send and receive PDF contracts constantly and need the ability to easily sign and edit them and send them on their way! 

If it is possible for me to sign and edit PDF's in workplace, or at least have the ability to integrate with other API's like pdffiller or dochub I will gladly upgrade my accounts to workplace.
