How can I make all the contacts on a SEEG electrode aligned middle and equally spaced using mne_gui.locate_ieeg?

Dear MNE,

When I use mne_gui.locate_ieeg to mark SEEG electrodes, it is difficult to mark each contact one by one, and I find that not all contacts can be aligned in a straight line, and I cannot ensure that the spacing between all marked contacts is exactly the same. (I also found the same problem in the document example Working with sEEG data — MNE 1.6.1 documentation)

In addition, although the contact diameter can be changed by adjusting “ch radius”, I don’t know their real size.

Is it possible to improve this GUI to solve these problems? For example, in Brainstorm, we only need to mark the deepest contact position and the position where the electrode enters the scalp, and type the electrode diameter, contact diameter, and spacing between contacts. Then we can accurately mark the position of this electrode and all contact positions.
