Implementing Custom Variables in RevenueCat Paywalls

Hello,

I'm interested in incorporating custom variables for each package within RevenueCat paywalls. Is this possible? To clarify, let's consider a scenario with two packages displayed on the RC paywall, namely pkgA and pkgB. For each package, I aim to integrate two custom strings: strA1 and strA2 for pkgA, and strB1 and strB2 for pkgB. In this context, these custom variables (strA1, strA2, strB1, strB2) are distinct from the variables mentioned on your "Displaying Paywalls" page. Essentially, I'm seeking complete flexibility in defining the values of strA1, strA2, strB1, and strB2.

Could you provide guidance on how to implement this?

Thank you in advance for your assistance.
