This request is to allow for Attribute selection on the Prior / Subsequent Features parameters when Adjacent Feature Attributes is enabled. Currently, only User Parameters can be specified (see image).

I'm not sure that a) this could be that useful -- as the expressions referencing the prior and subsequent features would have to be written knowing how many forward or back they are looking for -- and it is hard to see how that could be usefully done dynamically at runtime, and b) the amount forward or backward needs to be known ahead of when we run so we can allocate structures correctly. Having it dynamically change feature by feature would be very difficult to implement (if you suddenly asked to go back 10 features but previously we were going back only 5, we'd have released those oldest features).

Can we have an example of how this would be intended to be used so we can evaluate more carefully?
