Feature request: incremental strength round

Hi,

it will be useful to add the possibility to allow increase/decrease the weight on each repetition (ex: push up 3 x 12 x 10-15-20 = first rep 12 x 10Kg, second 12 x 15Kg , third 12 x 20Kg).

Will it be nice to be able to modify also the number of reps for each round phase.
