Pause Button/Possibility for historical download via QuoteManager

I dont know for whom and in wich situation this would not be helpfull, but for me, using historical data from IQFeed and only and directly downloading it into MC, it would be a great help, if it would be possible, to pause the hostorical download, instead of only being able to abort it.

When doing larger downloads via the QuoteManager and at the same time I want to reload a chart I am working on, that is not possible. I quess as soon the Quotemanger has sent the max amount of requests to IQFeed, the queue is just full and wont let any other request go thru.
Maybe some sort of priorization would also be a possibility, but a pause would be better I think. Since I dont know how long historical download will take, it might still run when markethours start and if then a "quick" reload is necessary, it even more sucks, if that is not possible.

Also saving something like a snapshot of the point/status a download has advanced would be great, it hopefully would make it possible, to close QuoteManager and resume after restart.
