Suggestion: custom isochrones when drawing tracks

[PingWing]

Hi,

I have a development suggestion:
Currently track drawing tool creates automatic isochrones on time change, that is, in 12 hour intervals. For long period planning this is ok, but similar visual stepping would help also in short-term tactics. Would it be possible to add customisable isochrones to the tracks when they are drawn? The settings could be, let's say, 1,2 and 4 hours.

Thank you for a great tool, and happy sofa sailing for everyone.
