Vary lay stake dependent on odds range

[heggahegga]

Hi - I'm trying to set up a rule to lay a selection by an amount that varies based on the odds range. Is this possible, and if so could anyone help explain how it's done please?

In my floundering attempts (!) I also considered instead just having a different fixed liability for the different odds ranges (which would serve the purpose of limiting the stake rather than fixing it), but I would then want to apply the rule to the same event but for each of my different liability amounts (i.e. applying multiple rules to the same event). And again I don't know if this can be done....!

Sorry, any help is greatly appreciated. I did search for an answer before asking this btw, but came up short!

Thanks!
