Can grid snap to center for connectors in Draw?

I am using draw to connect several text fields with connectors. To have as much straight lines as possible, I use the grid, which works perfectly for text fields in the same horizontal position.

If I have want to connect textfields of different size vertically however, this grid does not help at all, since the text fields either snap on the left or the right side, but never in center.

Of course, I could reduce the grid size to manually adjust the position, but to my mind, this is not what a grid is for.

Is there somewhere an option, to let the grid snap (only?) the horizontal center of text fields?
