Yes it will , use filter as below.

Can you not add the 'Dynamic media upload' step directly in your workflow?   Else if you meet the below conditions, like setting this scene7filestatus property , the ootb launcher should get called to upload it to DM . 

Like you mentioned ,one way is to keep such assets under a global/shared folder. Other than that  You may try and explore:- a) Asset collections: Collections store reference to assets  https://experienceleague.adobe.com/docs/experience-manager-65/assets/managing/manage-collections.htm...   b) Asset ...

do you see "Edit" option in 6.5.9 version? I think the 'missing edit option' is what was logged as a bug in jira.Not sure if you got a chance to check Jira details.

I think it may be an open deferred issue in Jira for 6.5.5 + version , try raising a support ticket .CQ-4330033

Can you check if the video has been processed in DM ? Have you published the viewers? Does your dms7 account have video processing capabilities?

I would suggest to remove these mandatory properties that you need only for image type from main custom schema and instead add them  under 'image metadata schema'  only.    

I meant , check your application schema , the metadata properties in excel are cascaded from there. Do you see mandatory metadata properties there , can you remove them from there?   There is no need to create another excel schema if there are no metadata properties specific to excel.

The custom application metadata schema will be applied by default  on your excel. If you dont want application metadata schema to be applied then you can add an excel metadata schema under application similar to psf  or use any existing schem and apply them
