turn 1d8+5 into 10d8+50?

I've set up a macro that rolls a variable number of attacks, but I've run into the issue of turning [d8+5] into say, [10d8+50] or whatever. If needed I can just make it roll [d8+5]*  10 or something, but would really love it if it rolled properly. Right now I have  /em launches a volley! /roll [[?{Number of Attacks=|10}d20>[[@{target|AC}-@{selected|att bonus} ]]]]d8  That covers the rolls, but for the flat damage modifier.... I am lost. Is there anything I can do or do I need to just go with 1 roll multiplied?

/r [[?{Number of Attacks=|10}d20>[[@{target|AC}-@{selected|att bonus}]]]]d8+(?{Number of Attacks=}*5) Hmm, but that always gives you 5 times the number of attacks not the number of hits. . There is no way to hold the variable number of hits with out the use of the API. 

Try: /r [[?{Number of Attacks=|10}d20>[[?{Number of Attacks=}*(@{target|AC}-@{selected|att bonus})]]]]d8+(?{Number of Attacks=}*5)

Okay. Thanks for the help guys. While it seems I cant get it in one, I didnt realize I could set a prompt variable for multiple things, so it does let me split the macro into "attack" and "hit" and work great. Thanks again
