Short answer- no. But it's easy to get an object to center by changing its translate coordinates to 0,0,0.
Select the object, open the transforms in the properties dialog, and change them all to zero.
I cannot see how that works. In the modeling mode, when you selected the CPs or even the whole model, where ever it is, its position in Transform, under translate reads X0,Y0,Z0. Changing it to 0,0,0 when its already set at that, would make no difference. In Model mode, it does not read the current location of the selected center of the CPs.
