3 questions regarding footnote format

Could anyone help poor me?

Question 1:

How to refer a chapter of one book in thisformat:

GeoffreyScott, The Architecture of Humanism(Doubleday Anchor Books, 1956), ch.2

If I input {Scott, 1956 #179@ch.2}, it willappear as:

GeoffreyScott, The Architecture of Humanism(Doubleday Anchor Books, 1956), p. ch.2

Currently I can only format {Scott, 1956 #179},and change the last section manually (delete the full stop and add “, ch. 2”),is there any automatic way?

Question 2:

What’s the name of the style?

GeoffreyScott, The Architecture of Humanism(Doubleday Anchor Books, 1956), p. 122

I changed Chicago 15th A to add “p.” and “pp.”, but isthere any style just like the one not needing any change?

Question 3:

When I format {Scott, 1956 #179; Lovejoy,1936 #482} it will appear as:

ArthurO. Lovejoy, The Great Chain of Being: AStudy of the History of an Idea: The William James Lectures Delivered atHarvard University, 1933 (Cambridge, Mass: Harvard University Press, 1936),Geoffrey Scott, The Architecture ofHumanism (Doubleday Anchor Books, 1956).

The question is how to make the two booksseparated by “;” rather than “,”

Thanks very much, questions may be silly,but if solved could save lots of time.
