Hi @Putu61
Here's a way without using professional tools: you can enter the price that you wish to set in the "minumum nightly price" field. Then select the dates (for example, select all of the nights in November together). In the pop-up screen, switch Smart pricing on. All of the selected nights will display the minimum price, except where market forces pull them up (you can edit those again if you wish - when you manually edit a night's price, smart pricing automatically turns off for that night)
