Option to Merge or Replace hasMany Field Values During Bulk Edit

[vqhdev]

Hello PayloadCMS team and community,

Currently, when selecting multiple items and editing a field with hasMany: true, it directly replaces the existing values with the new ones. I would like to request an option — such as a checkbox — to choose whether to fully replace the existing values or merge the new values with the existing ones. This behavior is demonstrated in the video I’ve created.

Source code: test-bulk-edit.zip
Run:

• pnpm i
• pnpm payload migrate
• pnpm dev
