Option to choose type of sales page conversions

It is frustrating that only form submissions are counted as conversions on Ontrapages. This effectively means we're only able to A/B test order form pages and/or squeeze pages. 

Arguably these are less meaningful pages to test than sales pages, because the prospects are either incredibly warm or cold respectively in both of those examples. The sales page is driving the revenue and yet we can't A/B test conversion rate.

Please make it so that we can select button clicks as conversions.
