How to configure the CNC URL of a message on the forum in Bitrix:US?

Question

1C-Bitrix

There is a forum on Bitrix with a default theme.
In the settings of the forum component, the url of a specific message is formed according to the mask:
"message" => "#FID#/#TITLE_SEO#/#MID#/"
where
#FID#- ID of the forum;
#TITLE_SEO#- CNC fragment transliterated from the topic name;
#MID#- Message ID.
Problems :
1. the url mask #FID#/#TITLE_SEO#/#MID#/is ignored by the forum component and replaced by default on any attempt to remove or replace elements from it #FID#and #MID#, although it’s #FID#not fucking necessary, given that it #TITLE_SEO#includes a unique topic identifier, and therefore the likelihood of a url match, in case of topic names , is equal to zero
and /#MID#/why the hell is not needed, since it is possible and customary to address individual messages by adding an anchor, not a directory
2. in the forum interface (where the last message of the topic is displayed), an #FID#/#TITLE_SEO#/#MID#/anchor is added to its address formed according to the mask, formed according to the principle #message#MID#
i.e. as a result, a construction is obtained, #FID#/#TITLE_SEO#/#MID#/#message#MID#
although it is needed for good #FID#/#TITLE_SEO#/#message#MID#
. Accordingly, the question is which files need to be opened in order to :

• get the ability to set the mask of the address of the message of the form /#TITLE_SEO#/#message#MID#without adding#FID#
  
• mow out the link to the last message of the topic adding an anchor #message#MID#
  

either to :

• the mask entered in the component settings was not replaced by the default one in case of violation of the invisible rules invented by the system developers
  

Answer 1

Here I see two options:
1) Rewrite the part in the form component that is responsible for parsing the address and selecting the component to display the topic itself.
2) Do not use a complex component, but split the forum into separate components and set CNC rules for each component.
