SQUID how to limit the speed of access to a specific site?

Question

Squid

Good afternoon, tell me how to limit the speed of a certain group of ip-addresses to a certain list of sites in Squid3, in particular to social networks.
For example, the marketing and PR department cannot cut the speed, but the rest will have enough, for example, a megabit.
There are manuals on how to cut the speed of the group of people,
but I did not find it for a specific site. is it possible?

Answer 1

in general, I had to compile the kernel with ALTQ anyway

Answer 2

Scovid is unlikely, look for traffic shaper
