How do I stop the changing of transaction dates when downloading from my bank.

When downloading transactions from my bank checking account, the dates are changed to when the item was processed by the bank. For Example: if I enter a check with a date of 8/15/2019 and the check clears on 9/10/2019, the date of the check is changed to 9/10/2019.
Is there a way to stop this from happening when doing the download? Thanks for your help.
