Support for Calculated Results

Hi,

I have been searching your boards, documentation and FAQs to find the answer to if there is a way to automatically calculate a shortcode value based on the input of other shortcode values? Like This:

[available]=[total]-[unavailable]
[available]/[total]=[available-percentage]

I enter the value for [total] AND [unavailable] and the value for [available] is calculated based on that? Once [available] is calculated it will be reused to also calculate [available-percentage].

Hope this is clear as to what I am trying to achieve?
