Can I modify my signature in a Adobe Sign workflow retrospectively?

Can I modify my signature in a Adobe Sign workflow retrospectively?
I have forgotten an addition to my signature and noticed after I passed the workflow to the next signer. 

I am the third signer out of four, the two ahead of me have signed successfully.

The Adobe Sign workflow was initiated by me. 

Any chance to modify my signature or do I need to cancel the entire document workflow and resubmit it again?
