Obviously not knowing the capabilities of the OP, I think possibly creating a POI might be a simple solution.
Maybe this will also be of use to anyone else who wants to know how to do it, even though it is a long-winded way to do it.
How to save individual Favourites in a POI
Because sometimes when transferring the Mapsettings.cfg file it does not always work, but what has worked every time (so far) is to create a POI of your own then add all your own favourites to the POI.
But, the first time it's a bit long-winded as you have to select the favourites one-by-one to add to the newly created POI.
Also once created if you want to add them back to favourites, just select the individual poi as a journey then followed by sending it to your saved favourites from your 'Recent Journey' file.
1. To create a POI:
a. Select, Manage POIs.
b. Select, 'Add POI category' and give it memorable name.
(I would suggest something like -1 Favourites that way it will always be at the top of your POI list, making it easier to find and use each time)
2. To add a favourite to the POI:
a. Select, Add POI.
b. Select your newely created POI.
c. Select, Favourite.
d. Select the favourite you want to add to the POI, and any information that you also want to attach such as telephone number.
This last stage (2) will have to be repeated for each favourite you want to add to your POI category,
so it might be a good idea to make a note of each favourite you have already selected so not to waste time selecting the same one more than once.
