If is possible to add commands in a Kit?

Its in the chat menu to add permissions to kits, I have them as server rewards by using Player Rankings by Ankawi.. You create a group (rank name) chat group add <group>Then you grant that group the kit permission , You can make the kit hidden or not as only those that have been granted the permission can redeem it.

is it possible for me to make a kit but instead of items can i get it to run a command on the server 

Example 

"cmd": ["$player.id Command"],

ive no idea how to implement this into a kit so any feedback would be helpful

I'm looking for this to give Daily Rewards from RP plugins ;)

For example, is there a way for when players redeem a kit, it runs a command for them to spawn in a vehicle or something? Like a sedan kit or anything like that.

Not currently but there are other plugins that revolve around spawning in vehicles
