Can the mixed boundary condition be changed into implicit form?

Hi, everyone.

Do you think it is possible to change the mixed boundary condition into implicit form?

The mixed boundary condition is defined as follows:

https://www.openfoam.com/documentati...bcs-mixed.html

As for as I understand, the cell value is taken from the previous iteration. But I need a implicit mixed boundary condition in which the cell value is unknown and calculated in the current iteration together with the face value.

Can you give me a clue? Thank you in advance.

I got that the cell value is unknown in the bc, therefore, it is implicit already.
