[Tagging] Motorroad does not apply to all lanes

[715371]

Hi,

I have a very, very special case here:

https://www.openstreetmap.org/way/318383959

There is a road with four lanes, but not all of them seem to be
motorroad. There is a sign which suggests that. I do not like to have a
separate way there, so I used the following tagging.

motorroad:lanes=yes|yes|yes|no

What do you think? Better ideas?

Regards
Tobias
