[talk-ch] Is it possible to adapt the "to" member of a "destination_sign" tag?

Hello and happy new year !

My idea is to be able to visualize together on a map the indications of a
panel and the corresponding paths. For the moment this is not possible,
because the 2 relations are not linked.

There are also signs that offer several routes to reach another point. In
this case, it wille be easy to visualize the various proposal. For example,
this sign shows 3 different routes to reach "Col de la Forclaz":


Best regards
