Is there any flexibility regasrding the layout and information shown in the preset approval process?

I have a client that is using the preset approval process for an app. We have ave been asked to edit the information shown to the approver in the mobile app, also to play around with the layout of the Approvals tab in the web app but have not found a way to do it.
Any suggestions?
Thanks
