Feature Request: Option to Limit/Restrict Clan Castle Donations Received

Dear Supercell Team / Clash of Clans Developers,

I would like to suggest a feature that would greatly improve the Quality of Life (QoL) for players during war and multiplayer attacks: An option to set hard limits or restrict specific units from being donated to our Clan Castle.

The Problem:

Often, when requesting specific troops (for example, Super Wizards and Super Archers), someone might also donate a random filler unit like a single Barbarian or Archer to complete the housing space. If a player forgets to manually delete that filler unit before attacking, it can ruin the entire strategy.

A prime example occurs during a Blimp + Clone Spell strategy:

• You drop the Blimp into the core of the base expecting to clone your high-value Super Troops.

• Instead, the Clone Spell targets the single low-tier Barbarian that came along with the request.

• The key troops end up not being cloned at all, ruining the entire attack due to an unavoidable accident.

Proposed Solution:

Allow players to toggle a setting or set strict rules on their CC requests—either by blocking unwanted troops completely or ensuring only requested troops can fill the CC slots.

Thank you for all your hard work, and I hope you consider this QoL addition for a future update!
