Swim data while rest

Hi,

During swim I display interval length which is fine for me (I wouldn't mind see the total length as well, instead of interval time).

While resting between intervals I want to see total length rather that last interval length.

Is it possible? 

Also, 

Why the decimal point, say 1000.00 meters? who needs this and it is always .00 anyway.

I rather have bigger & bolder fonts

Thanks

Guy
