This Quicken help page clearly says that the undeposited funds account is automatically created.

It also says that in that account you can select multiple entries to use as a combined deposit into something like a checking account. However, I cannot find this account anywhere. I cannot seem to create an account with that feature. I have Googled this for over an hour and searched the community to no avail. I have generated multiple invoices which is supposed to trigger the creation of the Undep. Funds acct. according to the link above. Undeposited Funds account is not an option when receiving payments and choosing where to send them. I am at a loss.
