ZC 1.5.7

I sell to places that have multiple locations, some have 15 or more, that buy from me. They would like a Regional Manager to be able to pull up orders, invoices, place orders through their login. All 99% orders are delivered directly by us. I don't have a security concern about this.

I've got the Orders and Invoices working great. I setup security to prevent anyone from just jumping into it. Added a couple flags on the tables to make it all work.

I would like to enable the Regional to be able to do Orders for an account if needed. I've been looking at the Admin side that lets you do it.
Before I start to really break that down how it is working. Is there an easy way to have a logged in user flip to another userID? I figured I'd save their ID in a session variable and have a button to bounce back to their main account at any time. I do not want them to use a Master Password.. although, I'm sure I can post the Form that would do that after pulling the email.

Thanks for all the help.

If I get it working 100%, I'll do it correctly to have installed as an optional Addon for approval.
