Run a sub process for each record in a selected folder

Hi all,

I have a process where a user selects a contact folder from a list on a preconfigured page. A sub process then needs to run for each contact in the selected folder.

I've read the article for Programmatically Using Section Folder Filters in Processes or Server-Side Code in Creatio | Customer FX and I have borrowed a script task for creating the list of contacts.

var sectionName = "Contact";
var folderId = "2d3c0306-1e43-4ba7-943b-a3d261b66897"; //I will pass this in from the preconfigured page
 
// get folder SearchData
var folderSchema = UserConnection.EntitySchemaManager.GetInstanceByName(sectionName + "Folder");
var esq = new EntitySchemaQuery(folderSchema);
var dataCol = esq.AddColumn("SearchData").Name;
var folderData = esq.GetEntity(UserConnection, folderId).GetBytesValue(dataCol);
 
// convert filter data to esq filters
var serializedFilters = System.Text.Encoding.UTF8.GetString(folderData, 0, folderData.Length);
var dataSourceFilters = Terrasoft.Common.Json.Json.Deserialize<Terrasoft.Nui.ServiceModel.DataContract.Filters>(serializedFilters);
 
// MUST INCLUDE using Terrasoft.Nui.ServiceModel.Extensions;
var folderFilters = dataSourceFilters.BuildEsqFilter(UserConnection.EntitySchemaManager.GetInstanceByName(sectionName).UId, UserConnection);
 
// now can include folderFilters as filters in new esq
var contactEsq = new EntitySchemaQuery(UserConnection.EntitySchemaManager, "Contact");
contactEsq.AddColumn("Id");
contactEsq.Filters.Add(folderFilters); // using the filters from the folder
var contacts = contactEsq.GetEntityCollection(UserConnection);

I would like to either pass the results into a collection or run a sub process for each contact directly from the script task.

Any help would be much appreciated,
