I've been using the methods described here:

https://quickbooks.intuit.com/learn-support/en-us/help-article/regular-payroll/create-reimbursement-...

in order to reimburse my employees for company expenses using various custom reimbursement types (supplies, meals, travel, etc.). For payroll this seems to work fine, but at the end of the support page linked above it says:

"After assigning the reimbursement to the employee, check your accounting preference to ensure it is posted in the correct accounts for exporting purposes."

Where can I check or edit this? As far as I can see, all reimbursement categories get summed into a single account named "Reimbursements", type=Expense, detail type=Payroll Expenses. How can I have these breakdown into the correct custom reimbursement categories (e.g. Reimbursements:supplies, Reimbursements:meals, Reimbursements:travel, etc.)?

Even better how can I map these expenses to the more general expense categories I already have on the books (e.g. Expense:supplies, Expense:meals, Expense:travel, etc.)?

I see an alternative method for reimbursing employees here:

Which I may do if this makes mapping to existing accounts easier, but for 2021 I did everything according to the first link, so how can I map these reimbursements in the Reimbursements account to the appropriate Expense subaccounts?
