Adding Pics and Videos to Posts + Time slots in minutes

Hi Support Team, i have a recommendation for the Tool. I used several before and found and worked with one before for a longer time which is called “Postoplan” by the company contenive .
In this tool it is possible to post to Instagram, Facebook, Telegram (formerly even to Whatsapp and Facebook Groups). But what i found there is the possibility to prepare a Post an also add Videos or Pics or PDF′s to the post and post it into the different social platforms. I used this function on Telegram to prepare an automated product presentation and schedule it to be repeated once a month at a special date and time. Now as i found Blog2Social I am really glad for the possibility not to need any other tool to write and prepare my posts for social media except my wordpress and website backoffice, but the function of adding pics or videos to an automated post row to the defined telegram group and the post time divided in minutes (not only in quarter hours) is missing for me in Blog2Social. Perhaps it is still existing but i did not find it actually. Can you give me some advice in this concern or is it possible to add these function to the tool??
