The relationship between effective top tube length and front center is discussed at: bikecad.ca/toptube_frontcenter.  I trust you will see from reading that page that you cannot directly input values for effective top tube length and front center at the same time.  Having said that, if you choose to drive your design by front center distance, you can still massage other dimensions to arrive at the effective top tube length that you want.  Once you've set the front center distance and head tube length, you can still alter the effective top tube length by changing fork length, fork rake, head angle, seat angle, bb drop, lower stack height, or the extension of the head tube above the top of the top tube.

See below, I have created a model of the size M Cinelli Mash based on the specs you attached.

I tried to do the same with the Kagero.  However, I found it a bit more tricky.  Part of me thinks those specs may not be accurate.  However, I will give them the benefit of the doubt and allow for the possibility that they define some of their dimensions differently than other manufacturers.
