How to update the task display name when the task is already created and not completed

Hi All,

I have a scenario where Appian task is already created with the task display name, for example as 'Task abc with amount $100".

Now when the user opens the task form, the amount will be recalculated in local variables and and are updated in database using Store Procedure execution function in local variables .

So, every time when the form loads, the amount will get refreshed and updated in Database as well.

Now my issue is ,when the amount is refreshed, the task display name should also get refresh,

for example if the amount is refreshed from $100 to $200 , then task display name should be 'Task abc with amount $200".

Note: The amount in task will get refreshed at the time of form loads, without any user interaction inside the form.

Please help me to achieve this.

Thanks in Advance.
