How to ignore invalid tag name instead of throwing a error

[yikaus]

Hi , 

I got the requirement to ignore the invalid tag name when execute a playbook 

eg .   ansible-playbook -t tag1 test.yml 

and I will get below error and fail the playbook

ERROR: tag(s) not found in playbook: tag1.  

What I expect is doing nothing if tag name is not exist  just like --skip-tags all

PLAY [localhost] ************************************************************** 

PLAY RECAP ******************************************************************** 

If anyway I can do that ? 

Thanks
