Allow for the addition of signage symbols for turn instructions.
I'm not asking for the ability to add all road signage (e.g. regulatory signage) as this would be overkill, but many countries include symbolism on big green signs to display additional services on a turn instruction without having to use lengthy text to do so.
While some symbolism exists in unicode/emoji form, these are not uniform across platforms and having country specific visual aids to add to signs would be a valuable way of informing drivers of additional services on their turn instructions.
The types of signs I would like to see added include:
* Caravan Parks
* Visitor Information
* Train Bus and Ferry services
* Public toilets
For example, the following two links are used extensively in Australia - https://www.qld.gov.au/transport/safety/signs/service and https://www.qld.gov.au/transport/safety/signs/tourist - on big green signs, and also on tourist drives. While not all are useful to be added to turn instructions, there are many that would be.
This would be a meaningful way of informing drivers about services available along their route.
If any get in it would be really important to add the airport symbol, I remember many times driving to the airport looking for that. If it was right in front of me I would not miss it.
