Screenshots spanning several HTML blocks

I need to automate very specific screenshots. I know that “captureScreenshot” captures the visible screen, “captureEntirePageScreenshot” captures the entire screen and that “storeimage” captures blocks of HTML. The latter is almost what I’m looking for, except that my screenshot straddles several HTML blocks. Is there a command that could do this? THANKS !

StoreImage uses an xpath as an input, maybe you find an element that actually contains all the textblocks you need.
