Recurring topup of Crypto Vault in Fiat Currency


I’d like to be able to set up a automated recurring daily payment into my Bitcoin vault for 10€ per day. At the moment you can only specify the recurring amount in a fixed bitcoin value e.g. 0.001BTC. But in this case the value from my EUR wallet varies according to the exchange rate.
Please advise if there is a way to topup at a fixed EUR amount…or if this is a planned feature in the roadmap.
