Aid should be distributed through these checkpoints. Each parcel of aid, from where ever it came, should be stamped with “Brought to you with the Assistance of Pakistan” or some thing similar.
If each of these Small posts along the border get sized up into towns with medical NGOs and food distribution networks it can re-write the narrative for what this border and its posts are all about; a humanitarian life line to Afghanistan. The aid infrastructure built now, can be an enduring anchor for these posts along the border. Hospitals, food storage facilities, trading facilities/markets.
The tribes on the other side of the border will have to work with the posts (even if begrudgingly) on our side to receive aid or trade through the border or get medical help. Instead of 4-5 points of crossing, if the number of crossings or aid distribution points was in the dozens; but build up in this manner, the people on the other side would have to accept these points as part of their lives. It will also end the excuse that families are being divided if these dozens of crossings are places Afghan roads come up to the border or could be built up to the border and linked with Pakistani roads.
If there is Fasad in the sectors near any post, that crossing point could be shut down, on security grounds for days or more, to send a message.
Having said All this, I trust the matter will be handled diplomatically, but this is a way to deal with two problems at once, speeding up distribution of international aid to try to prevent the on going humanitarian disaster in Afghanistan from getting worse and by changing the perception of the border into a “border of peace”.
