Advertise a new route without entering a full list

We have a decent number of routes advertised from one of our sites and it’s fairly clumsy / error prone to have to specify all of the routes every time we want to add a new one. Is there a CLI option to basically just ADD a new route to the existing list?

Ex. instead of: sudo tailscale set -advertise-routes=xx.xx.xx.xx/yy, (etc)

Something like

sudo tailscale add
