Add radio command that allows players to request a rucksack of goods be taken from the main base and sent to any outpost... to allow easier response to friendly enclave resource requests: Fill 'Er Up, Demand for Food, Meds Please, Materials for Everyone.
Once the radio request is made... it could take a short while for the resource to arrive at a nearby outpost... allowing the player to work on a nearby quest while waiting.
This radio command can be obtained either as an enclave benefit, or even a new legacy boon:
Boon Name: Supply Lines
Leader Type: Courier/Trucker/Delivery
