You want to sign with the SAME signature multiple times in the same file? A digital signature? If so, that's a complete no-no, procedurally and technically wrong. The signature always applies to the whole file, the visual appearance is irrelevant. If you want just a visual stamp it's a different story.
SAME signatures, the form is for training verifications so each line requires a trainer and a trainee. I want to be able to sign all the trainer blocks at once or the trainee blocks all at once
