show subsections in toc for multiple sections but not all sections

In a beamer presentation toc I would like to show only the section headings for most sections but show also subsections headings for some sections. I know this is easily obtained for the current section only. But I would like to show subsections headings for the current section and another one. Basically, instead of using hideothersubsections option, I would need an option where it is possible to specify the numbers of the sections for which to hide subsections hiding. Does this option exist?
