Custom command to be executed even if preceding command fails

end command gets executed even if a preceding command fails. E.g. browser.waitForElementIsVisible("non-existing-item", 500).end()

I need to write a custom command that gets called always same as end command. If I try browser.waitForElementIsVisible("non-existing-item", 500).saveVideo().end() or browser.waitForElementIsVisible("non-existing-item", 500).saveVideoAndEnd() the command does not get called if prev command fails.

Is there a way to achieve this?

Thanks Tomas
