How to do focus stacking with Sony A7?

It seems that software such as Helicon Remote or the EOS utility that allows you to choose focus points remotely make focus stacking much easier.

I couldn't find something like that with Sony A7. Even Sony's remote camera application does not have that feature and it turns out that the helicon remote control is only compatible with Canon and Nikon.

So, my question is if I want to stack the focus on the software with Sony A7, is it my best option to manually focus with the lens ring or if there is software that will make it super easy like the Helicon remote control or the EOS utility.
