Supplementary toll on motorways with vignette

How to include a supplementary toll information within vignette-obligatory motorway? There are such situations in Austrian tunnels - both vignette and a supplementary section toll are needed. When planning routes this can make a difference.

That’s a very good question. I’ve never thought about it, even though the Arlberg Tunnel is right in my area. I’m very curious to hear the answers.

To add and clarify: the Arlberg Tunnel carries the S16 expressway through the Arlberg. The Austrian vignette is valid on the S16. The annual vignette costs €103.80 for passenger cars. The tunnel then costs an additional €12.50 per passage.

Perhaps unrelatedly, I thought about specifying fee= (eg =included , =extra / =additional , =dedicated ) for features inside features before Fee for museums that are *mostly* free? - #5 by Kovoschiz
This could be on toll= ; or better it can be more specific eg toll=network;route for separately tolling the network=AT:S-road and route=road , or is it toll=network;tunnel for the Tunnel alone?
If toll=yes is to be kept, or semicolon multival avoided, it might be eg network:toll=yes + route:toll=yes / tunnel:toll=yes to show both the network= and route= / tunnel= have its own toll=yes
