Tracking for Zeydoo offers with multiple landers

When perusing offers on Zeydoo, sometimes there are multiple landers/"creative mix". This seems less than ideal for tracking purposes, and there seems to be no way to create multiple offer URLs with custom settings (e.g. one lander per URL). What is the standard way to handle this? Do you:

• Run all of them and optimize as if there was no offer-side lander variation? (thought being: they've already optimized, but this doesn't account for so many variables such as geo, site/zone "categories", etc)
• Run a single one (e.g. the "Landing" option below) and build your own landers (maybe based on the lander previews shown), then track normally?
• Run campaign with one of the landers selected, collect data, change lander settings in Zeydoo offer, run another campaign, collect data, lather, rinse, repeat?
• Other options?
