Creating a task based on 2 different deals in 2 different funnels?

Question

Bitrix24

Friends, good problem...

There are:
-Funnel 1: Deal 1, Task for Deal 1
-Funnel 2: Deal 2, Task for Deal 2, Task to complete Deal 2

Deal 1 in Funnel 1 is completed after Task for Deal 1 is completed .
Deal 2 in Funnel 2 does NOT complete the Task for Deal 2 field , but is waiting for Task for Deal 1 and Task for Deal 2 to complete , to set a Task to complete Deal 2 .

It is not known which task will be completed first, task for deal 1 or task for deal 2 .

The question is, how in Funnel 2 to create a Task to complete Deal 2 after completing the tasks Task for Deal 1 and Task for Deal 2 ?

Answer 2

In the current version of Bitrix24, it does not provide a solution to your problem within the framework of standard features.
For the cloud version: you will need to write some application that will know about tasks 1 and 2 and about deal 2 that needs to be closed.
The boxed version is the same, but you can do it without the application.
