Use Current Value If Unwired

Status: Duplicate

It would be beneficial if nodes had the ability to retain data from their previous execution. Along with "Use Default If Unwired" it would save memory allocation and coding time if there was a "Use Current Value If Unwired" selection which would retain the node's value and pass the last executed value.

This figure illustrates one application where "Use Current Value If Unwired" would save memory and increase performance instead of using multiple property nodes or local variables for retaining the output data. It would also eliminate extra wiring in every case this node is not used.
