staking plan help

hi new here and would like a bit of help on a staking plan as i,m a perplexed on how to do it...i,ve downloaded the dlambert and tried to adjust it but am a bit lost....i need a staking plan  to bet as follows ..its a double martingale with a 20 step bet so if it wins 2 in a row it should in theory be in profit...as we get a few wins on the way...so the staking plan is 1..1..2..2..4..4..8..8...16..16..32..32.64..64..128..128..256..256..512..512..1024..1024..i know the minimum is £2 so the 1st 2 bets cant  be used ...i need it to bet 3 random selections per game leaving only 1 selection it can lose on..i want it to bet instantly before any odds change also ...the betting sequence goes up the chart and resets either when in plus or has 2 wins in a row..could anyone help me with this please..

Hi hartscape, sorry to bump this up but have you found a work around on this yet?
