Hi Zoho Team,

We are regular users of the Documents module in Zoho Books and appreciate its ability to keep financial records well-organized.

However, we’ve noticed a limitation:
There is no way to attach a document from the "Documents > Files" section to an already entered transaction such as a Bill, Expense, or Invoice.

🟡 Current Issue:
The "Add to" option only allows creating a new transaction (bill, expense, etc.), but doesn't allow assigning the document to a transaction that was already entered manually.

🔵 Requested Feature:
Please enable the ability to:

• Attach existing documents to already recorded transactions (Bills, Expenses, Invoices, Credit Notes, etc.)

• Or add an option to search and link existing transactions directly from the Documents section.

This small enhancement would greatly improve document traceability and help businesses that:

• Receive documents via email later,

• Use autoscan limits wisely,

• Or manually enter transactions first and organize documents later.

Looking forward to your consideration and positive response!
