MDS Drawing Leader Line of Slab to avoid crossing of lines

Can anyone give solution on how to avoid slab leader line clash?
A client requested to rearrange the leader line automatically to avoid clash.

This maybe a challenging request as a drafting admin.
On MDS drawing, I manage to control the clashing position of SLABs.

But now the clients are requesting to avoid leader line clash also which I think very difficult to control due to there's a lot of different support model with different cases.

Below are some example output of MDS drawing (with encircled clashing leader line):





I hope anyone can help. Thanks.
