Double time-Help with Editing

[Jazzpiano]

Hi All,

I was trying to figure an easy way to take a tune (End of a Love Affair) in this case, that is written as a 4/4 and change it to a double x feel to be played say, twice as fast but with the changes going by at the same rate.
Therefore there would be TWICE as many measures as the original.
Is there an easy way to do this in the editor.

I have done this the "backward' way with Cherokee (64 measures) in 4/4,
converted to 32 measures of 2/2, so one can hear a slow rhythm section playing but play double time (iE 16th notes at half the tempo) to practice relaxation.
But can't figure out the reverse.

Any tips would be appreciated.

Here's my example of the Cherokee chart.
Cherokee 1 - Ray Noble


Thanks
