SP - Battles & Sieges Pre-Seige Indicator of Siege Tower Wall Position

[DrDragonlance]

When pre-placing troops, I would like some sort of an indicator where Siege Towers will go.

While the Siege towers are moving, I work to aim siege equipment on the location, but I don't always get it right and the siege tower ends up somewhere I wasn't expecting.

I have no desire to memorize the location of siege towers for every Town and Castle, so a pre-battle indicator would be great.
