How to use Selenium via Python on Chrome to change multiple downloaded file directories without having to launch the web driver & link more than once?

You can use the driver.command_executor method to achieve this. It allows you to interact with the current browser session.
You can use this method to change the download path, without relaunching the web driver.

The code snippet is given below-

You can change the 'downloadPath' parameter as per your requirement.

#initially setting the download path to current directory
driver.command_executor._commands["send_command"] = ("POST", '/session/$sessionId/chromium/send_command')
params = {'cmd': 'Page.setDownloadBehavior', 'params': {'behavior': 'allow','downloadPath':os.getcwd()}}
command_result = driver.execute("send_command", params)

#your code to download the file

#followed by changing the download directory
#for example here I'm changing it to data folder inside the current working directory

driver.command_executor._commands["send_command"] = ("POST", '/session/$sessionId/chromium/send_command')
params = {'cmd': 'Page.setDownloadBehavior', 'params': {'behavior': 'allow','downloadPath':os.getcwd()+'\data'}}
command_result = driver.execute("send_command", params)

How to control the download of files with Selenium + Python bindings in Chrome

The path you declared for the default directory is invalid. Either escape the back slashes or provide a literal string.

options = webdriver.ChromeOptions()
options.add_experimental_option("prefs", {
"download.default_directory": r"C:\Users\xxx\downloads\Test",
"download.prompt_for_download": False,
"download.directory_upgrade": True,
"safebrowsing.enabled": True
})
driver = webdriver.Chrome(chrome_options=options)
