Is there any way of using the ink picture control method on a userform to enter the handwritten signature into a bookmark.

I've seen a previous post relating to a "stored" signature, but is there a way to add the ink picture on a userform instead.
Ideally want to use a userform to add handwritten signatures to documents.

The inking feature in word will not always be a option unfortunately, so therefore ideally was looking to create a userform that will always allow a signature to be entered.

Any help would be appreciated.
