Plug-in linking possible on the same channel?

Hi -

Please can I ask… is it possible to link two or more plug-ins of the same type on a multi-channel channel?

So I have a 5.1 channel and I want to EQ L&R and Ls&Rs in exactly the same way with two instances of exactly the same plug-in, one assigned to LR, the other assigned to LsRs. Can I link the plug-ins so that if I change one it mirrors the change on the other plugin instance?

Ideally the plugins would be multi-channel capable. But they are not.
