General question for real pilot about STAR/Approach relationship when planning

I set up the route below to EGPF Glasgow, but all STARs coming from the south end at the awkwardly placed LANAK, leaving an acute turn on to the approach to 05.

What do I do about this? Is there a way to improve this in Navigraph? (should the dotted section be filled in with something solid - like what?)

Or do I just hope I get vectored by ATC before I get to the acute turn onto finals?

Thanks for any advice.
