Customizing Frame output from DITA

I have years of experience with DITA but structured/unstructured Framemaker is new to me.

I am trying to style PDF output from DITA using the native Frame template/rendering engines (i.e. not the DITA-OT) in FM 2017.

I've been using the 'Save Ditamap as" > "Book 2017 with Framemaker Components" workflow. I've hit three stumbling blocks:

1. Additional front matter: Doing <notices href="copyright.dita" toc="no"/> does not pick up the copyright page.
2. Additional back matter: My corporate style requires a back cover
3. Customized front cover content. I need to support additional text fields on the front cover. I've populated the bookmap's booklibrary mainbooktitle aand booktitlealt elements, but they are concatenated into one variable (Chapter Title Name) in the conversion process to unstructured Frame.

For questions 1 and 2, is there a way to customize the list of components generated when converting?

For question 3, how can I adjust the mapping between bookmap elements/subelements and unstructuted Frame variables used in templates?

Thanks!
