First of all, there is 1 figure group in Google Slide. Here, how many copies I want, the copies of the shape group are created according to their positions. but there are placeholders in the group, {{NAME1}} and {{PRICE1}}, {{NAME1}}, {{NAME2}},{{NAME3}} and so on for as many placeholders as I want to create copies.
{{PRICE1}},{{PRICE2}},{{PRICE3}}
Let the copies change as, for example, if I want 4 copies{{PRICE1}},{{PRICE2}},{{PRICE3}},{{PRICE4}}
And
{{NAME1}}, {{NAME2}},{{NAME3}},{{NAME4}}
Let it change one by one like this
