Making a mixture of Alias and trigger??

I currently have an alias called cbash *

require "wait"
wait.make (function ()

Send ("swing %1")
Send ("swing %1")
wait.time (7)
Send ("STAND")
Send ("evoke pentagram")
Send ("clot")
Send ("clot")
Send ("clot")
Send ("clot")

Note ("@@@@@@@Check shield. Sip or sleep/med if needed.@@@@@@@@")

end)

However, instead of waiting, I would much much rather just wait until a certain line is sent before continuing the rest of the script.

For example, in pseudocode:

send swing
send swing

if I get message "You have recovered balance"

send swing
send swing


Is this possible?
