Using Tabs for Indentation, Spaces for Alignment

Hi, we are trying to get tabs for indentation but spaces for alignment to work (some background: https://www.emacswiki.org/emacs/SmartTabs ). We have enabled both the "Use tab character" and "Smart tabs" options in the Editor -> Code Style -> Java -> Tabs and Indents settings tab but cannot see a difference from leaving the smart tabs option unchecked.

Example: we are trying to create a String using multiple string concatenations: String foo = "foo" + divider + "bar" + divider + "buz" + divider;.
Now for improved code legibility, I would like to separate the statement to span multiple lines in such a way, that we have following lines:

• String foo = "foo" + divider +
• "bar" + divider +
• "buz" + divider;

Further, and this is where the actual problem arises, I would like to indent each line with an equal number of tabs but then align the second and third line using spaces in such a way, that the opening double-quotes of "foo", "bar" and "buz" are in the same column. Even with smart tabs enabled, IntelliJ does not automatically follow this alignment (even in line 3, after manually using it in line 2) and in fact breaks my manually created alignment, since it uses tabs to do the 'continuation indent', rather than spaces (useless, if you are trying to align). Obviously it also removes any alignment spaces when I have IntelliJ format the source code.

Is there a way to configure IntelliJ to behave in the desired way? Thanks!
