It is possible to cache Navionics web map?

The url of tile such as:
http://backend.navionics.io/tile/13/4749/2322?LAYERS=config_1_10.00_0&TRANSPARENT=FALSE&UGC=TRUE&navtoken=TmF2aW9uaWNzX2ludGVybmFscHVycG9zZV8wMDAwMSt3ZWJhcHAubmF2aW9uaWNzLmNvbSthdGY4ZmlnZ2I5

As I mean, it's possible to describe via "URL Template" provider, but "navtoken" are changed every day. Navtoken may be get from http://backend.navionics.io/tile/get_key/Navionics_internalpurpose_00001/webapp.navionics.com with some rules.

Thus, the need a periodically get a navtoken, and use it to get tiles.
