[...] We´d like to connect the issues directly with the import. But we cannot insert the explicit issue number, because the parent issues don´t exist before import. And the second reason is that we want to us the import file as template, so there cannot be specific numbers.

Useful would be a kind of dynamic link between the issues. [...]

I think you can already achieve such with the current implementation for #950.

From #23396#note-2:

When importing issues, the content of a the parent colum can be:

• a number without # (eg: 10) => the parent will be the 10th imported issue
• a number with # (eg: #10) => the parent will be the existing issue with id=10

and from HowTo_import_issues#Parent-Issue:

If the field starts with an #, the issue with that id is referenced. If the field contains a number it references the index of the issue in the import. Note that it's not the line number as line 1 contains the header

So, a CSV file looking like follows (note the parent column values with the #-sign omitted):

Subject	Startdate	Duedate	Parent
taskA	1/1/2016	12/31/2016
taskB	1/1/2016	12/31/2016	1
taskC	1/1/2016	12/31/2016	1
taskD	1/1/2016	12/31/2016	3
taskE	1/1/2016	12/31/2016	3
taskF	1/4/2016	12/31/2016	4

would be imported creating the following issues tree:

taskA
 -> taskB
 -> taskC
     -> taskD
         -> taskF
     -> taskE

And, starting with not-yet-released Redmine 3.4.0, you can even use a CSV file like:

Subject	Startdate	Duedate	Parent
taskF	1/4/2016	12/31/2016	2
taskD	1/1/2016	12/31/2016	5
taskE	1/1/2016	12/31/2016	5
taskB	1/1/2016	12/31/2016	6
taskC	1/1/2016	12/31/2016	6
taskA	1/1/2016	12/31/2016

which would be imported creating the following issues tree (equal to the example above):

taskA
 -> taskB
 -> taskC
     -> taskD
         -> taskF
     -> taskE

This extended feature behaviour is implemented through a separated issue (#22701).
