there's nothing built into to the package to allow doing this by default. That said, the rapid paging block does already cache pages that have already been previously loaded, and with a little work you could probably use this existing functionality to get it to do what you want if you're good with javascript.

1) create a new list of links to those pages you want to preload.

2) create a new rapid paging rule that is applied to each of those pages, and set the target to some other element on the page.

3) set both that new list of links and *the parent* of that target element to display:none so that neither affects the look of the page

4) this is the hard part: trigger click() events on each of those links, but do it in a way where each successive click event only loads after the previous one has completed loading, firing it within that the rapid_page_load event:

$(document).bind('rapid_page_load', function(e, data) {
triggerNextCachingLinkClick();
});

Best of luck
