How to set Google Chrome to ask for a download location

is there a way to get ubuntu / nautilus ask for where to store a file when downloading instead of automatically placing it in the download folder.

a similar question was asked here but without an answer. How to change default download location to an SD card?

this is more a general question than a specific situation, but as example:

while browsing (google chrome) i decided to download asustor adm 3.0 beta and would like to place this directly on the nas. Instead of downloading it to the download folder and then relocate it.

In Google Chrome you can set to always ask for a download location.

Go to Chrome settings and check this option.
