Is it possible to implement theme preprocessor on specific template in drupal 8? What I am here trying to achieve is simple. I want to change the default drupal "submitted by" field to only render day and date but not the time when the node was created. To do so I want to preprocess the field which is being evoked by field.html.twig. But apparently, I don't want to run the preprocess on every field by using hook suggestion "field". Hence i created the specific template "field--default--node--node-submitted-by--blogs.html.twig". Now I want to implement theme preprocessor on this specific template. Can achieve on based on template suggestions or not?If so how?
If you implemented your own template suggestion then it's as easy as writing a function with the following name:

function THEME_OR_MODULE_NAME_preprocess_field__default__node__node_submitted_by__blogs(&amp;$variables) {
}


The main thing to take care of is to convert the hyphen characters (-) to underscores (_).

Good luck!
