Programmatically set the selected item in dropdown on form open ?

Programmatically set the selected item in dropdown on form open ?

Hi all,
I have a form in a Creator App with a dropdown of 15 items.
On opening the form, I want the first item to be selected.
After hitting submit, the same form is shown but this time I want the second item selected.
And so on to item 15.

How would I achieve this ?

I see there is a pattern of field aliases discussed here  https://www.zoho.com/forms/help/settings/field-alias.html . would I use this ?

e.g. https://forms.zohopublic.com/.../?fieldalias_gc=Group1&fieldalias=option2

Thanks in advance,
Nick
