No, unfortunately not. At least not for the ones that are available from us. I haven't tried this, but I'd assume that if you make your own activity, you'd be able to reach the HttpContext and use the values here rather than the ones supplied in the pipeline settings. But I don't think that that's what you want...?

I assume you ask this question because you have an external system in charge of the integration through which you want to set specific parameters which is a common way of doing things. Unfortunately not wery well support in Import/Export, so if you want to control the behavior of a built in activity remotely, you'd have to upload a new pipeline file using FTP or WebDAV and then run this file with the pipelinerunner.aspx. It's not pretty, but it would work, and looking at a .pipe file I'm sure you'll easily find the nodes to modify to accomodate what you want.
