Multiple loops

I am sure this has been brought up in the past as an enhancement but thought I would ask anyways.

Lets say you have a 20 mile bike look you want to complete 2 times or you have 2 different loops you want to combine together this cannot currently be done in the training logs.  You either have to select the route you did 2 times and change the distance which is not a big deal but if you want to combine 2 routes it cannot be done, is this something that is being worked on?  I would think it would work kind of like the sport section where you could just add multiple routes, but then again I am no programmer.

Thanks.
