We do not support that, nor do we have the manpower to add anything like that.

It is a good thing to support, but unfortunately we are unable to. If you have the programming ability, you may be able to code an extension to 1.3.15 to do it yourself. But we would not support it in 1.4.0 which is the current in-development version, due to the progression of the Bitcoin SV ecosystem from legacy payments based on monitoring the blockchain to P2P payments where party A and B directly exchange transactions. This change in model would render the 1.3.15 extension non-portable to the eventual 1.4.0 release.
