I have a problem with when using align = baseline for the flex container

I have a problem using align = baseline for a flex container. Other components have an empty text positioned before the component to align buttons with other input fields . Because TwinColSelct does not have this, I tried to add a before element with css, but I had a problem because the flex-direction of the twincolselect is column and then the before element is positioned above. I would be nice, if the component could support this out of the box.

Version is 2.5.1

Frankly speaking, I have no idea how it should behave in such case. It is a complex component with lot of child elements, so the whole idea of applying baseline alignment is not very straightforward.
