I'm sure there are many companies like ours that have a old style "non-TMS" implementations where props and eVars are hard coded into pages. Where this is the case it can be difficult to change/reclaim props and eVars that have been implemented particularly if access to the relevant IT function is difficult to obtain.
I would like to have a setting in the admin settings that allows me to make break the link between what is coded in the page and what ends up in the analytics database.
i.e. a setting that makes props and eVars act in the same way as context data variables; requiring a processing rule to map the variable in the incoming metrics call to the variable in the backend database.
I think this would massively increase the flexibility for those of us stuck with difficult to manage implementations.
