Allows copying of signals from power poles to constant combinators, snapshotting the values at the time of pasting.
This could be helpful if you have a combinator setup to calculate something that won't subsequently change. Copy the resulting signals into a single constant combinator, then deconstruct the calculator to remove those extra entities and save those precious UPS!
Obviously this is limited to the number of signals that the target combinator can hold. If there are more signals than that, the exact signals that are chosen is undefined as it fills the combinator with as many as it can.
Mod works with any entities of type "electric-pole" and "constant-combinator" so should work with any modded items of those types.
