Changing Data Value from the Frontend of Qlik

[Asuod_]

Hello, 

I have an app where i want to change the data value based on the user input from the dashboard. Say i have the following table below. How would i go about setting up a dashboard to where they can filter on the ID and Attribute to change the Value and I cant utilize a QVD (company reasons) or vizlib writeback functionality. My initial thought is a variable input and partial reload but any guidance is appreciated. 

ID	Attribute	Value
1	Color	Red
1	Age	21
2	Color	Green
2	Age	48
3	Color	Purple
3	Age	36

If i select ID =1, Attribute = Color, Value change to Green then i want the table to read

ID	Attribute	Value
1	Color	Green
1	Age	21
2	Color	Green
2	Age	48
3	Color	Purple
3	Age	36

You could maybe use the function getfieldselections() which will input your selection - and depends on the volume you could use some if statements to counter what is visible in the values
