ANYONE know of a zap to fUSD$ invoicing process. Example I want to buy a 10fUSD product, don't want to go converting @ BTCsat:fUSD conversion on time stamp ? Plug in digits and conversion happens. #grownostr #growzapEconomyNow #KISS #zapnostr

Wallet of Satoshi will make a “one off” invoice for a dollar increment. Tap the grey up/down arrows and it swaps between sats and bucks. 
I’m not sure if I totally understand the question… But it sounds like you want to be able to send an invoice for, let’s say $1, without having to do the conversion manually? I can do this in Wallet of Satoshi… See 2 photos.
First click the lightning thingy, then add the dollar amount. That’ll bring you to a new screen where you can enter the amount and if you notice a little up-and-down arrows that’ll toggle between fiat and Satoshi’s. 
isn’t there a way to do it with strike?
