Sorry for for that.... I thought the "imoprt" block was a type of block that I
could create from the modtool.
but
In the import-block I can import modules. But I can still not import actuall
code into my top_block and I can not call functions from the import-block. What
I want to avoid is to add code in the top_block manually since I'm normally
using the GRC to generate the top_block.

Try the block search (magnifier button in GRC), type in "import" :)

Hi again
I have a MPSK SNR Estimator Probe and a Function Probe that
calculates the SNR.
I can not find any information regarding "import" block.

Companion. I would like to add some additional code to the top
block but I still want to be able to work with the GRC. Is
there a way to add this extra code without the code will be
