Alternate / multiple camera rolls in iOS?

I use my iPhone camera extensively at work to take photo's that need to be uploaded to our company's server. I used to have to carry around a separate camera, just to take these photo's; but find it far more convenient to simply use what I carry around with me 24/7.

What has always been problematic is segregating my personal photo's from those taken for the company. I will typically shoot about 100-150 photo's a week. When importing personal photo's on my Mac (to Aperture) or to my company's server (Using ACDsee on one of the company's PC's) I find it very time consuming to go through my entire camera roll to select/deselect photo's that should or should not be uploaded to either system. Inevitably; I often end up accidentally uploading (& deleting from iPhone) company photo's to my Mac or personal photo's to the company's server.

Is there any way to create a secondary camera roll that I can switch to; while at work (switching back to personal camera roll at all other times) so that I can simply upload the appropriate camera roll to my personal or office computer systems?

I prefer to do this with the built-in camera app; since my primary method of pulling up a camera is via the up-swipe motion on my lock screen. Any/all suggestions are appreciated. (With exception of requirements to Jailbreak; since this is often not an available option & can reduce reliability of the phone.)

Thanks
