Last Layer Practise?

[Skrato]

Hi,

I have an average of about 24 seconds, and I want to improve my last layer speed right now, because it is actually very slow. I heard a while ago that there was a spreadsheet or some program that gives a scramble keeping the first two layers intact so that you can practise the last layer, but I can't find it, can someone link me to it please?

Thanks speedcubers.

This looks like it might do what you are wanting. I haven't been able to get it to work on my computer so I can't test it:
